【摘要】 针对ＣＣＤ电视摄像机在精密数字图像测量等研究领域中应用的要求，为进一步提高数据采集系统的精度，研制了一种对面阵ＣＣＤ电视摄像机的各像元信号进行直接采集的系统。着重在信号相关双采样电路（ＣＤＳ）、高速Ａ／Ｄ转换电路、图像数据存储与ＩＢＭ－ＰＣ微机之间的数据传输进行实验。更多还原

【Abstract】 In order to meet the requirements of CCD TV camera in precise digital image measurement and other fields, we have developed a data collecting system which may collect the pixeldna directly from CCD plane array camera and can improve the accuracy of data collecting. Thefocuses are placed on the experiments of the coherent double samping(CDS)circuit, high-speedA/D converter, data storage as well as the data transmission beween the CCD camera and IBM-PCmicrocomputer.更多还原
